Perforated Front Cover

*Ref. page 26

If equipped, the perforations in the front

cover allow early separation to reduce

rotor loss and increase capacity. This

can also reduce cracks and splits in

corn, and improve distribution on the

cleaning shoe.

Separator Perforation

Covers

*Ref. page 27

When installed, reduces the amount of

broken cob and stalk on the return grain

pan. Reducing the total MOG will reduce

shoe loss and improve grain sample.

Excessive Rotor

Loss

1. Reduce Concave clearance

Excessive Shoe

Loss

1. Increase ground speed to optimize

2. If the shoe is overloaded on the right

side, install concave cover(s) over

the first and/or second concave(s) on

the right side to improve shoe distri-

bution.

Bar and Wire Separator

Grates

*Ref. page 23

When installed in the front separator

grate section on the left and right side,

these will reduce rotor loss by giving

the corn an exit point. In drier condi-

tions, these grates can contribute to

shoe loss, due to the addition of MOG

on to the shoe.

6

Excessive Rotor

Loss

1. Soft (rubbery) corn cob - Increase Con-cave clearance so that more crop is present in the rotor cage for better crop-on-crop threshing

2. Hard corn cob - Decrease Concave clearance to the diameter of the cob so that the crop is threshed from the cob and separated early in the processor.

Excessive Shoe

Loss

1. Increase ground speed to optimize ma-

chine capacity

2. If the shoe is overloaded on the right

Concave Leveling and Indexing Adjustment

1. From inside the cab, adjust the concave clearance to the

smallest clearance achievable

2. Put the Rotor Gearbox in Neutral

3. Remove Concave sections #2 and #5 from the left hand

side of the cage, as shown in Fig. 1.

4. Rotating the rotor, determine which rasp bar is closest to

the bottom of the concave frame at sections #2 and #5.

5. Using a 1/2” Allen Wrench, or similar tool to gauge 1/2”,

determine if the gap between the bottom of the concave

frame and the two rasp bars found in step #4 measure

1/2”, as shown in Fig. 2, Measurement “A”.

6. If one or both measurements are incorrect, loosen the

stop bolts along the top of the concave frame, as shown

in Fig. 1, “A”.

7. Adjust the front and rear adjusting bolts inside the

springs (Fig. 3) accordingly until the rasp bars at con-

cave #2 and #5 both measure 1/2”. This will ensure that

the concave is level with the rotor, and that suggested

settings will be accurate.

8. Tighten the stop bolts at the top of the concave frame,

shown in Fig. 1.

9. Tension the front and rear springs to 5 5/16 in.(135mm),

as shown in Fig. 4, Measurement “A”.

10. In the cab, go to the Maintenance Menu, select

“Calibrations” and calibrate the concave.

Grain Loss Sensitivity

Nothing can replace the judgment of the producer when de-

termining an acceptable amount of grain loss from the com-

bine, however, the grain loss monitor in the combine can be

calibrated and adjusted to communicate to the operator

where grain loss is coming from and how significant it is. This

knowledge improves the efficiency of operation, and can

determine critical adjustments that must be made to improve

performance.

There are three loss sensors on the rear of the shoe and two

loss sensors on each side of the rotor, at the rear of the ma-

chine. The impact made by the grain lost and other crop de-

bris is shown on the bar graph at the top of the next page.

There are multiple factors that impact the suggested sensitiv-

ity. See a couple of examples below.

Corn - Rotor and Shoe loss sensitivity should be initially set

between 80% and 90% each.

Soybeans - Chopper Door Down (to include shoe discharge),

Rotor loss sensitivity should be initially set at 80%-90%, but

the shoe sensitivity should be set at 30%-40% due to the

increased MOG at the rear of the shoe.

The important piece to remember about the grain loss sys-

tem is that when the bar graphs move to show there is grain

loss, the operator understands how much loss is actually

exiting the combine, so that optimum ground speed and com-

bine settings can be achieved.

See page 2 for Grain Loss Charts.

Automatic Header Height Control

1. Calibration - In order for Automatic Header Control to be

engaged, a successful calibration must be saved.

A. Navigate to the Maintenance Menu (Purple Hand)

and select “Calibrations”.

B. The header will calibrate automatically, lowering

completely to the ground, raising all of the way up,

tilting left, tilting right, and centering itself. This

process takes a few minutes.

C. The minimum and maximum voltages for all of the

sensors on the combine and the header are saved

during the calibration sequence.

2. If one or more of the Header Calibrations is not success

ful (red X), complete the following process to adjust sen-

sor voltages.

A. Level the header and set it firmly on to the ground in

the working position.

B. Navigate to the VMM3 Analog Inputs Screen

C. Adjust each sensor on the left side of the header and

each sensor on the right side of the header to 1 volt

using the VMM screen as a reference.

D. Adjust the lateral tilt sensor to 2.5 volts using the

VMM screen as a reference.

E. adjust the sensor for feederhouse height to 1 volt

using the VMM screen as a reference.

Fieldstar

The C2100 shows Instantaneous and Average Yield

The yield shown is only valid after a proper calibration.

Press the “Play” button in the screen on the next

page to begin counting pounds that will be measured on

a grain cart with a scale, or from a scale ticket. A “Stop”

button will appear in its place

When the grain that will be weighed has been harvested,

press the “Stop” button

Take the known weight in Pounds and insert it in to the

white box that appears next to “Weighed” grain.

Accept the new calibration factor

Moisture is also shown on the C2100

Like yield, the moisture must be calibrated properly with

a trusted source in order to be used.

Example… If the moisture shown on the combine is

15%, but the Elevator records this grain at 18%, the user

must ADD 3 to the “Moisture Offset” shown on the next

page to complete calibration of the moisture sensor.

Alarms and Dry Yield Reference require an accurate

moisture calibration
